srovlal SPECIFIC A'IION-vformng part of Letters Patent No. 742,108,dated October ,20, 1903.

Application filed February 18,1903. Serial No. 143,939. (No model.)

To all whom it may concern.-

Be it known that I, JAMES WOOD, a citizen of the United States, and aresident of Noroton, in the county of'F-airfield and State ofConnecticut, have invented a newand Improved Stove, of which thefollowing is af'ull,

clear, and exact description.

The prime feature of this invention is a certain improved constructioninvolving an airjacket surrounding the stove, so that lhe'cold airentering at the bottom may be heated by contact with the walls of thestove and discharged from the top of the' jacket to heat the surroundingair or be carried o to another apartment of the building in which thestove is placed.

The invention also involves a novel airfeeding attachment for thestove,which allows me to introduce pure atmospheric air into thecombustion-chamber of the stove at will, thus bringing about thoroughvcombustion of the escaping gases. 4

This specification-is an exact description of two forms of my invention,while the claims dene the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a partofthisspecification, in which similar characters ofv reference indicatecorresponding parts in all the views.

Figure l is a perspective view of the invention. Fig. 2 is an enlargedvertical section thereof. Fig. 3 is a section on the line 3 3 of Fig. 2.Fig. 4 is a section on the Vline 4 4 of Fig. 2, and Fig. 5 is ahorizontal section of al modied form of the invention.

ct indicates the body of the stove, which in itself does not differ fromthe usual cylinderstove, it being provided with a cap a', a feeding-doord2, an ash-door a3, and a base a4, all of any desired form. l

b indicates the jacket, which extends from directly above the base d4outward from the sides of the stove and thence upward parallel therewithuntil the cap a is reached. The jacket b turns in at its front edges, asindicated at` b', to meet the walls a at each side of the door a2. Thisforms an inclosed space surrounding the body of the stove and heated byradiation from said walls. As shown in Figs. 1, 2, 8, and 5, air-inletpipes c are provided at the lower portion of the jacket, and at theupper portion of the jacket air-outlet communicateV with the tube c andwith the atmosphere by means of atube c', all of which is shown in Fig.5.

vTo facilitate the complete combustion of the gases escaping from thefuel, I provide in the upper rear portion of the stove-body a avertically-disposed bafle-plate f, fastened to 'the walls of the stoveby means of brackets f. From this baffle-plate f atube f2 projectsforward, the plate`f being perforated at the rear end of the tube, so asto permit the air to pass from said tube through perforations at theback of the baffle-plate. The tube f2 projects through the front wall ofthe stove, andQin this tube is fitted a telescopic tube f3, having ahandle f4 at its front end and a series of perforations f5 adjacent tosaid end, it being noted that the said bafe-'plate also servespractically as asupport for the inner end of said tube f2 within theupper part of the combustion-chamber of the stove. When the tube f3 ispushed inward for its whole length, the openings f5 will be covered andthe tube f2 will be closed. When, however, the, tube f3 is drawn out, asin Fig. 2, there is a clear passage opened through the sections fs `andf2 to the space back of the baffleplate j', vthus supplying fresh air tothis space and supporting the entire combustion of the combustiblesubstances in these gases. This arrangement for admitting fresh air alsoincreases the draft through the iiue d, and thus prevents any of thegases from the stove escaping into the roorn'or building in which thestove is placed.

By means of my invention a maximum degree of heat may be drawn from aminimum supply of fuel, since the jacket b and its appurtenances providefor the utilization of practically all of the heat developed, while theair-supply devices fif3 enforce complete combustion of the fuel.

Various changes in the form, proportions, and minor details of myinvention may be resorted to at will without departing from the Vloospirit and scope thereof. Hence I consider myself entitled to all suchvariations as may lie Within the intent of my claims.

From the foregoing it will be noted that my improvements constitutepractically an attachment Which may be applied to many forms of ordinarystoves at present in use substantially without any alteration thereof.

I-Iaving thus described my invention, I claim as new and desire tosecure by Letters Patent- I. The combination with a stove having a doorin the front thereof, of a jacket surrounding the rear and sides of thestove and having inturned edges at its top, bottom and front, thusforming a completeinclosure surrounding the stove, said jacket having anair-inlet opening at its bottom and an air-outlet opening at its top,tubes projecting from the jacket at said openings, a tube-headerencircling the stove and communicating with the lower series of tubes,and an air-pipe eX- tending from the header.

2. The combination with a stove, of a vertically-disposed baille-platelocated Within the combustion-chamber thereof, in proximity to latterbeing perforated at the point of such support, and means for controllingthe passage of air through said tube to the rear of the plate.

3. The combination with a stove, of a vertieally-disposed baffle-platelocated Within the combustion-chamber thereof, in proximity to the exitof said chamber, an air-supply tube leading from the exterior' of thestove, and supported at its inner end by said plate, the latter beingperforated at the point of such support, and means for controlling thepassage of air through the tube to the rear ofthe plate, said meanscomprising a perforated tube slidable with reference to the firstnamedtube.

In testimony whereof I have signed my naine to this specification in thepresence of tWo subscribing Witnesses.

JAMES WOOD.
